SyntaxThe IUnivariateDistribution type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | Entropy |
Gets entropy of the distribution.
|
| Mean |
Gets the mean value for the distribution.
|
| Median |
Gets the median value for the distribution.
|
| Mode |
Gets the mode value for the distribution.
|
| Quartiles |
Gets the Quartiles for this distribution.
|
| Support |
Gets the support interval for this distribution.
|
| Variance |
